Oleg Vladimirovich Losev (sometimes spelled Lossev or Lossew in English; Russian: Оле́г Влади́мирович Ло́сев; 10 May 1903 – 22 January 1942) was a Russian and Soviet scientist and inventor who made significant discoveries in the field of semiconductor junctions and the light emitting diode (LED). Although he was never able to complete formal education and never held a research position, Losev conducted some of the earliest research into semiconductors, publishing 43 papers and receiving 16 "author's certificates" (the Soviet version of patents) for his discoveries. He observed light emission from carborundum point-contact junctions, constructing a light-emitting diode (LED), did the first research on them, proposed the first correct theory of how they worked, and used them in practical applications such as electroluminescence.
